Answer 1

'Le hice varias preguntas , a todas las cuales contestó'

there is a point i could not understand in that sentence. Do i have to use las cuales in that sentence? Can't i transport what i mean without las cuales? and what is the meaning of that form?

I asked him/her/you several questions, all of which he/she/you answered.

See Rodrigo's post for better form.

The only way I can think of to say that without that preposition (las cuales) is to make a compound sentence:

"Le hice varias preguntas, y (él/ella/usted) las contestó todas."
"I asked him/her/you several questions, and he/she/you answered them all."

Answer 2

'le hice varias preguntas , a todos las cuales contesto'

there is a point i could not understand in that sentence. Do i have to use las cuales in that sentence? Can't i transport what i mean without las cuales? and what is the meaning of that form?

It would sound as awkward as is does in English to omit it.

I asked him/her various (several) questions, to all of which he/she answered (I am assuming that should be contestó)

In Spanish you cannot end a sentence in a preposition as we do in English. In English I would move the a [to].
...all of which he/she answered to. (you cannot omit the of which in English either.) Even if you re-wrote it in English...he/she answered all [of them] it is awkward to change the all from an adverb to a noun.

Answer 3

I think your sentence is bad.....
le hice varias preguntas, a las cuales contestó
or
le hice varias preguntas, las cuales contestó todas

In this case "las cuales" is refering to "preguntas"
