I had a world religions class last semester and I found it very interesting, lemme get my notes and see if I can help you.
Sun Dance: Well looking back on my test I missed that question
So moving on
Four Sights: A decrepit old man, diseased man, a corpse and a woman weeping over it, and a religious ascetic
Four Noble Truths:
- To live is to suffer
- Suffering is caused by desire
- Suffering can be brought to cessation
- The cure to suffering is to follow the noble 8 fold path
Five Precepts: (I'm assuming just the normal 5 and not the monks and nuns five?)
- Do not take life
- Do not take what is not given
- Do not engage in sensual misconduct
- Do not use false speech
- Do not drink intoxicants
Easy way that helped me remember: don't kill, don't steal, don't have crazy sex, don't lie, don't get wasted
Eight Fold Path:
- Right Views
- Right Intentions
- Right Speech
- Right Conduct
- Right livelihood
- Right Effort
- Right Mindfulness
- Right Meditation
Now the lotus I'll just give a short little explanation, because that's basically all I can remember. A lotus is a good symbol of Buddhism because buddhism teaches that one has to look inside of oneself to discover meaning and reach peace, union between mind, body, soul, and to reach nirvana and be enlightened. The actual flower bloom of a lotus is inside of it. Also here's a phrase that I remember from a film we watched, "the space in the heart of the lotus". I think it was expressing that inside each of us, and inside a lotus (lotus being a symbol for us and our hearts) there is a space, and within that space is the universe, we just have to unlock it and find it.
Hinduism: Have no idea what you mean by milestones and festivals, sorry.
Five Pillars:
- Salat - Prayer
- Zakat - Purification (literally meaning a tithe, a tax)
- Saum - Fasting
- Hajj - Pilgrimage to Mecca
- Shahada - Witness, the english translation of their declaration of beliefs is loosely "There is no God but God and Mohammed is God's prophet."
Those were just taken from my notes, sorry that I don't have more of an explanation.
-Muslims face towards Mecca when they pray.
-Ramadan, just google it

I don't really know much about it besides that it is a time of fasting.
- Don't know the meanings
Judaism we didn't study but I'll tell you what I know of it.
- A menorah is a type of candle holder, I believe it holds 13 candles?
Christianity, I go to a catholic school so I've had to take religion classes for a long time, I'll see what I can do.
- Don't remember much about when the schism happened, only thing I remember was that schism sounded like it should be some dirty word
- Constantine was the first roman emperor, he spread Christianity throughout Rome, I can't remember much more.
-Easter is supposed to be the most important because it was when Jesus was resurrected or whatever
- I heard once that the importance of the fish was that it was a way for early Christians to communicate that they in fact were Christians to each other (since it was against the law to be one basically) and that a person would draw half or part of the fish, and if the other was a Christian, they would finish it, though User's sounds right too
Shoot me a PM if you have anymore questions, I'll be on for maybe 20 more minutes.
***I did not mean to offend anyone or their beliefs, I apologize if I messed up on part of describing a religion, please don't take offense and please correct me!***
