can i use the word "fear" instead of "afraid" .

Could you Check out the errors in the above sentences and also give me the explanation .
Can a sentence contains multiple "if" clauses and one sub-ordinate clauses?

Within limits, a sentence can contain more than one 'if' clause. Your sentence needs some help:

When you are walking on the road, if you see a dog and (if you) are afraid of it, it will follow you; if you aren't afraid of the dog and if you turn and look at it, then it will go away.

I suggest you omit at least the words in parentheses.

Yes, you can use "fear":

When you are walking on the road, if you see a dog and you fear it, it will follow you; if you don't fear the dog and turn and look at it, it will go away.

One can say "if you have/don't fear", but it sounds a bit dated, IMO.
