I currently build 5 range squads for every 1 damage squad and 1 armor squad but now people are starting to tell different ratios than what I have and from each other. Some say 2 range: 1 armor and others say 3 range: 1 armor. I don't know what to build? Please help me!

Most use 2 range 1 armor, or a combination very close to that. For example for infantry 21 range for every 9 armor etc.

Winning battles is about superiority. 1.5 squads for every squad faced. Under this ideal circumstance 2/1 ratio is good. I like to use a squad of proper equipped range for every squad and 1 armor squad for every 3. Damage are useful in close fights. If you can not get superior numbers and need to fight then load up on the damage. But ultimately its about knowing what your opponent has and knowing what you have can win.And the best battles are with the fewest losses. Range is the key to this as a first round win is desirable. The armor is to keep the expensive range alive.

I always use a 21:9 range to armor ratio and I do not build squads with just range and squads with just armor.

2 squads with all range and 1 with all armor is good with xp hunting, since u can easily adjust the number of armor and range u bring into the xp hunt.

however this means u'll need to move at least 2 squads every time to make sure there are armor going with ur range

but to answer about damage, unless u're going for an equal battle (which is pretty bad and should be avoid at all cost), don't use damage in ur army.
