Have VS Have Been

can have and have been be used together to maintain parallelism.

eg : 1) My classmates have visited the monument or have been to the city.

2)They have a drug prescription with a dosage too low to be effective, or have been taken off a drug too soon

Have is present perfect tense while have been is present perfect continuous tense.

Have is present perfect tense while have been is present perfect continuous tense.
Is there a question in your post? I (and probably others) are confused...
Thanks.

Actually in the examples you have quoted, "have been" is also used as Present Perfect.

They have been here many times before. - Present Perfect

They have been coming here for the past 10 years. - Present Perfect Continuous

I don't explicitly remember any sentence on GMAT that tests "perfect continuous" tense.

By the way, "have" can also be used as Simple Present:

I have a car.

So, it really depends on the context.
