Depending on what is counted, there are between 68 and 91 sovereign countries with at least one star on their flag—this will be explained further here, and there is a list of all these countries below.
First of all, it depends on whether or not a depiction of the sun is considered to be a depiction of a star (scientifically, the sun is a star like any other). This makes a huge difference, and even then there is some ambiguity. If the answer is “yes,” then it is questionable whether to include the flags of Japan, Bangladesh, Niger, and Mongolia. These countries have simple colored discs on their flags which, by cultural traditions, do represent the sun, although it would not be apparent to an outside observer (Palau and Laos also have prominent discs on their flags, but these represent the moon, not the sun). If the answer is “no,” then it is questionable whether to include the flag of Nepal, which has two depictions that are said to represent the sun by tradition, although to an outside observer these would probably pass as non-sun stars.
Second of all, it depends on what exactly is counted as a country. There are 193 U.N. member states and two observer states, but there are other countries that are still partially recognized. Most notably, Kosovo, Taiwan, and the Sahrawi Arab Democratic Republic have star(s) on their flags (In Taiwan’s case, it is the sun). These countries, although not UN members or observers, have significant international recognition (there are other disputed territories that have flags with a star, but none are recognized by more than a handful of countries, so they’re not included here).
Lastly, it depends on which variations of the countries’ flags are included. For a small number of countries, there is a distinction between a state flag and a civil flag, often differing by one version having a coat of arms. The state flags of Bolivia, Costa Rica, Ecuador, and El Salvador have depictions of the sun (and for Bolivia and Costa Rica, other stars as well) in their state flags—present in the coats of arms—but not on their civil flags, which lack a coat of arms.
Here is a complete list of significantly recognized countries with at least one star on their civil, state, and/or national flag, including the depiction of the sun, and including Kosovo, Taiwan, and the Sahrawi Arab Democratic Republic (FYI, many lists found on the internet regarding this topic are inaccurate and incomplete; certain countries’ flags, like that of Moldova, have one or more stars which are small and not easy to see, but are present):

To show how many countries there are ! I don't really know why they use stars ... maybe just just for looks .
coffin flags ARE American flags, so there's the same amount of stars on each.
The U.S. has 6. No other countries have flags there.

Many flags are like that. A couple of examples are the French and Italian flags.
