Expressions-- How to say these in Spanish?

[Ashis]

Hallo friends, how are you all?

I have a question. I have learned Comparative Adjectives in Spanish but do not understand how to write these type of expression like;

As soon as
As long as
As mach as

Are there any rules to write these expressions in Spanish? please help.

Great, thank you.

I'd say,

Tan pronto como
Mientras que / En la medida en que
Tanto como (I take you meant "As much as")

Not sure of specific rules, but the above are the translations.
