Yes, those tuplets are all notated "correctly". Notating tuplets is the same as notating any sort of rhythm; make the subdivisions as clear as possible. This depends on how you want the tuplet to be subdivided. It could be subdivided into 2 quarter notes, 4 eighth, 1 dotted quarter/1 eighth, etc. It depends on the song and arrangement. If all the voices are playing that rhythm together the subdivison isn't as important, while if it were an independent line clearer subdivision is much more important.
On the first line, first measure you can see how all 4 eighth notes are expressed in the tuplet clearly. If this were a repeating line it might be best to notate the first bar this way while using a more compact version, such as the third measure, for the rest of the repeats. However, the third bar is not bad either, especially if you're subdividing it as dotted quarter/eighth the whole time.
For the second line either one would work, though the two eighth rests would be clearer at first glance.
On the third line, measure 7, it might be wise to notate the dotted quarter note as a quarter tied to eighth to make it clearer, but again it depends on how you want to subdivide it. If measure 8 were following the same subdivision as written in 7 I would divide the dotted quarter into eighth and quarter.
Measures 9 and 10 are interesting in that you could justify further dividing them into sixteenth note 8-tuplets, especially measure 10. Turning the rests into sixteenth rests would more clearly show that. Since there are only 3 sixteenth notes it's not as important, but the more you add the more important I would rate it.
To reiterate, notating tuplets involves identifying their weak and strong beats and emphasizing those, both of which depend on the type of musical line you wish to write and what effect you're going for. If all the beats are relatively equal, or only the first is, then you should make it clear how the full tuplet is laid out. Since this is a 4 note tuplet made of eighth notes the standard procedure would be to make sure all 4 of them are clearly marked rather than obfuscate them with longer rhythms.
