Should I text her again after one word replies?

One short reply tells you almost nothing. A pattern of short replies over several days tells you more. Check whether she ever writes more than a line, whether she asks you anything back, and whether her replies get shorter on personal topics or longer on things she cares about. If she sometimes answers your questions with questions of her own, the thread has life in it even if the messages are small.

Also look at the context. Is she replying from work, mid-evening, or late at night? Did she just say she was busy? If she tells you she's at a wedding or on a shift, the short reply is just logistics. If she hasn't said anything about her day and still gives you nothing, that's a stronger sign she isn't especially keen right now.

When someone is replying minimally, a message that asks for effort will usually get a minimal reply back. Yes or no questions, or ones that ask for a fact, are easier to answer than ones asking how she feels about something. Add a small specific detail so there's something concrete to react to, like a place, a show, or a plan.

Keep the message about one thing. Two questions in a text will get answered with one word, usually the easier of the two. Pick the one you actually want to know and ask that. If she still only gives a word, don't push harder. Accept the answer and stop chasing for more.

Give it a reasonable gap before you follow up. If she replied within a day, waiting one to two days before your next message is normal. If she left your last message unanswered, one follow up with a fresh, light point is fine. After that, a third message in a row means you're chasing, and it usually ends the thread.

If she goes quiet after your follow up, leave it alone for a week or more before trying again, and only if you have a real reason to message. If her reply comes back with the same low effort, that's your answer. Move on and put your time into people who match your energy.
