There are a couple of tutorials on practicing.

Here is my standard reply to the question.
Any practice schedule has to consider your daily life schedule, current skill level & current learning topic.
This is a general list of how to approach learning & practicing.
1. Practice your guitar some every day.
2. Practice earlier rather than later, so you won't run out of time & then feel guilty about not getting in your daily practice. If this means getting up an hour eariler, then DO IT. This is always preferable to waiting until the end of a long, frazzled workday, then rushing through a tired, uninspired, frustrating practice session. And staying up an hour later to do it!
3. Start with something fun that you can already do. A song, a chord progression, a scale, a melody. Anything, but something you can already do that is FUN. Even if this is the only thing you do, or have time for, at least you played your guitar, got your fingers & mind moving musically & it was fun. :)
4. Eventually change to something that is problematic. Something new you are not good at yet. Scales, chord changes, memorizing notes, reading music notation. Spend time learning something new & challenging.
It is important to keep in mind that this is new stuff you aren't good at yet. Be patient with yourself. Remember that everyone has to climb the leaning curve. We all had to go through this difficult stage. Some people work faster, some slower, but everyone has to put it their time.
Try to enjoy it. :)
5. End with something fun that you can already do. Again, a song, a chord progression, a scale, a melody. Anything, but something you can already do that is FUN. This lets you end your practice session on a good, productive note. You can leave the guitar satisfied rather than frustrated. You will be encouraged about your skill & look forward to playing the next time or day.
You can do all this once a day or several times throughout the day with breaks in between. This list can be completed in 30 minutes or 8 hours.
Let me know if you have more questions. Best of success!
