Would it have a problem if we take combined vaccination of this all.

It can both harmful and beneficial. better to go with single one. Right now we don't have information on how this cocktail will work in biological system. It can cause serious allergic reactions also if all taken together.
For some reasons it always advisable to stick with only one Vaccine, and I believe countries will go for only one Vaccine (Pfizer, Moderna or AstraZeneca). High-income countries including US, Germany UK, Japan etc have already signed a purchase agreement with Pfizer before the vaccine approval for market. I believe high-income countries will stick with one vaccine –Pfizer. As for low- and middle-income countries (LMICs), the cold chain requirement for Pfizer and price for Moderna and Pfizer will make it much more inaccessible to LMICs. AstraZeneca vaccine will be a more suitable choice for LMICs (low price and storable within refrigerating temperature).
