Coherent states may serve as useful and important tools in physics because of their unique properties. Recently, for a graphene layer placed in a perpendicular magnetic field and a crossed electric field, coherent states have been introduced. In this paper, we evaluate the entanglement and some non-classical features such as squeezing and photon statistics properties for coherent states and their superposition; we then investigate how these properties can change by varying the fields. By defining these states as two qubit states and using concurrence, we realize that all states are entangled and by increasing (decreasing) beta\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\beta$$\end{document}, the ratio of electric field to magnetic field increases (decreases) the entanglement of coherent states. Also, states exhibit squeezing with sub-Poissonian statistics in some range of the related parameters. However, for large values of the coherency parameter and beta\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\beta$$\end{document}, all states represent Poissonian statistics with no squeezing in quadrature operators.
