It depends on the context.Have you received these samples during May to July. Please double check and confirm to me even I noted the delivery note with your signature.
:tick If you are talking about very specific samples among a group of samples, I would use these.
:tick Otherwise I would simply use the samples.
:tick Don't forget your question mark in the first sentence, you are asking a question (?).
Anyway, here's how I would put it. I'm not certain I understand your sentence though, it's a bit nebulous.
Have you received the samples from May to July?
This implies that the person you are talking to has received the samples.
Have you been receiving the samples from May to July?
This means that the person has received some samples but not all of them yet. He/she is still receiving some.
Please double check and confirm to me even I noted the delivery note with your signature.
This part is really confusing. It's really hard to say without the context. If would suggest that next time you wish a sentence corrected you provide a full paragraph so we can understand the context.
I guess the right way to put it might be:
Please double check the samples and contact me. I personally made sure that your information was on the delivery note.
