1. The correct one. Look+ forward+ to + gerund.
4. The correct one. Without (prep) + gerund.

Yep - it can be mentioned that in
1. "to" is a preposition, not part of an infinitive, so a gerund has to follow.

Unfortunately both 4 and 5 have other errors. May I suggest;
We produce reports without 'compromising/compromise to' quality or accuracy.
or
We produced a/the report without 'compromising/compromise to' quality or accuracy.

or we produce reports without compromising to quality or accuracy. ( I still don't like this sentence. Who would buy reports that do not offer quality or accuracy? You never know, though.)

"Without compromise to" means "without sacrificing"; so basically, the sentence means that the company maintains quality and accuracy while producing reports.

"compromising" is ok but you used "comprising, comprise" in the original sentence.

When in doubt take out or use other terms such as
"I hear you" and "I am hearing you" If you choose to use a verb, "look," following the choice with the verb as in "I am..." "I LOOK forward to hearING from you."

4 and 5 are both incorrect. "We produce reportS without comprOMising quality and accuracy." or "We can produce a report without comprOMising quality or accuracy."

3B = i am looking forward to hearing from you (would be ok as well), but still not as good as number 1 in my opinion

Actually I look forward to... and I am looking forward to... are both grammatically correct. The latter is generally considered more informal.
