Yes, it is correct.
You are correct to use "who" and not "whom" because "who" is the subject of the clause "who has sent him."
"I was sent the present" is correct, passive but correct. The first sentence needs "to" before "me" to be correct--"The present was sent to me."To make the sentence active, identify who sent the present. For example, "Billy Bob sent the present to me."
"You and him" is correct in a sentence such as, "I sent the tickets to you and him," versus a sentence such as, "You and he should send the tickets to me."
The sentence is almost correct. However, it should be "You sent it through DHL yesterday."
The correct grammar for this sentence is: "When did you send it?"

First it is an "invoice" not a "voice". Then the correct sentence is:- Dan reported that the contractor had sent in his invoice.

i have sended you my cv or i have sent my cv Save
"Have sent" is correct. "Have sent" is the past participle form of the verb "send" used in present perfect tense.
No. It is unclear in this sentence who sent a letter to who. Maybe it should be: Thanks for confirming the receipt of my letter.
